Box-plots of liver V20Gy for DIBH versus FB in right breast only (a) and right breast plus RNI (b) groups. Statistically significant reductions in the absolute volumes of liver receiving 20Gy were seen with DIBH for both breast only and breast plus RNI groups. The red cross indicates the group mean and the whiskers extend to 1.5 times the IQR, with n = 10 per group
